Good news is the piece is available at NAPA and O'Reilly's for only a couple of bucks.
thats probably it, i havent got to it yet but on the driver side i used a regular bolt w/ same threading and a lock nut on each side of the cable end to use as a spacer to help get the connections tight and have good connection. i'll probably just do the same on the other side considering i've never once had problems with the second battery conections loosening or that battery not charging
